To all whom it may concern g Be it known that I, THOMAS RBnpenn, a citizen of the United States, residing at Gloucester, in the county of Essex and State of Massachusetts, have nvented certain new and useful Improvements in Traps for Befrigerator Drain-Pipes, of which the following is a specification.

The present invention relates to certain new and useful improvements in the construction of traps for refrigerator drain pipes.

trap whereby the trap is arranged at the upper end of thedrip pipe and the said drip pipe is not dependent forsupportupon either the back or sidewalls of the refrigera tor.

\Vith this and other objects in View, the invention consists in certain novel combinations and arrangeinents of the parts as will more fully appear as the description proceeds, the novel features thereof being point constructed in accordance with the invention. Fig. 2 is an enlarged vertical sectional view through the upper end of the drip pipe and the trap, and Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 2.

Corresponding and like parts are referred to in the following descriptlon and lndicated in all thevlews of the drawings by the same reference characters.

Specifically describing the present embodiment of the invention, the letter A designates the body portion of the refrigerator. The walls of the refrigerator are preferably formed of spaced sheet metal plates 1 having an air space 2 between the same, each of the said sheet metal plates being lined upon the interior thereof with a layer of paper 3, a layer of linofelt 4L, and then a second layer of paper 5. The air space and linofelt provide a perfect insulation which prevents heat from being conducted through the walls of the refrigerator. The walls of the refrigerator are also made air tight, thereby preventing any moisture or odors from work- ED Tiaras PATENT OFFICE.

The walls 10" y and 11 only extend upwardly for a portion of the whole height of the ice chamber, and the corrugations therein run vertically so as to provide for a "proper circulation of air within theiee chamber; The bottom of the pan 8 has a cent :11 opening for thecirculation of air, and is inclined toward a discharge opcninglfljwhich has a nipple 1 3 applied thereto. icsbefore stated, the icerack 0 is made in one rigid piece which is bodily removable from the refrigerator, thereby leaving practically a single chamber within the refrigerator with continuouswalls which can be easily cleaned and are perfectly water tight. If necessary or desirable, the re frigerator could be cleaned by placing it upon its back and entirely or partially filling it with Water, since the interior thereof is both air and water tight.

The drip pipe 14 is arranged at the hack of the refrigerator and has the lower end thereof passing loosely through the bottom of the refrigerator. This drip pipe is provided at the upper end thereof with a cup 15 having a plate 16 arranged therein. The upper extremity of the drip pipe extends through the bottom of the cup and projects into the interior thereof, and the plate 16 which is secured to the sides of the cup extends over the top of the drip pipe and has the free edge thereof extended downwardly into the cup so as to project below the upper vided for preventing the free circulation of air through the drip pipe into the refrigerator, the plate .16 being inclined toward the free end thereof so as to deliver any drippings into the cup. A looped piece of spring wire or metal 17 is carried by the trap and projects upwardlyfrom the plate 16, the said looped spring member being chambers.

adapted to be forced into the discharge nip ple 13 and to frictionally engage the same so as to supportithe drip pipe and trap in position. The drip pipe is thus supported without the necessity of fastening it to the back or side of the refrigerator, which is a .the top of the drip pipe the less likelihood there is to be odors permeating thejfood This drip pipe 14 may be conveniently arranged at the rear of the shelves 18 of the food chamber, the said shelves being loosely mounted upon the shoulders 19 so as to be easily removed from position at any time. i

As has been previously stated, the pan 8 and ice rack 9, and. corrugated sides 10 and 11 are formed in one rigid construction so as to be bodily removable from the refrigerator when it is desired to clean the interior ofthe same. The rear end of the pan 8 rests upon a shoulder 6 at the back ofthe refrigerator, while the forward edge of the pan is formed with a lip adapted to rest "upon the-cross bar between the doors of the ice compartment and provision compartment. v

Having thus describedthe invention, what I claim as new and desire to secure by Letters Patent, is

1. In a refrigerator a drip pan formed with an outlet, a removable drip pipe adapted to be supported under the outlet of the Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

drip pan and in communication therewith, spring means for holding the drip pipe securely in operatlve position with respect to the said outlet, and a trap carried by the drip pipe. 7

2. In a refrigerator, a drip pan formed with an outlet a drip pipe, a trapat the upper end of the drip pipe, and a spring member carried by'the trap and adapted to engage the outlet of the drip pan to support the trap and drip pipe.

3. In a refrigerator, a drip pan formed with an outlet, a removable drip pipe, a trap at the upper end of the drip pipe, a looped spring member projecting from the trap and adapted to frictionally engage the outlet of the drip pan to support the trap and drip pipe in position.

at. In a refrigerator," a drip pan formed with an outlet nipple, a drip pipe, a cup carried by the upper end of the drip pipe and through the bottom of which the drip pipe projects, a plate arranged in the cup with the free edge thereof projecting downwardly below the upper end of the drip pipe so as to form a trap, and a looped spring member projecting from the plate and adapted to be inserted in the outlet nipple of the drip pan, so as to frictionally engage the same and retain the trap and drip pipe in posi-' tion.
